Fans snapped pictures of stars David Tennant and Michael Sheen as they prepared to film scenes around the Hippodrome Cinema
They were joined by Dame Siân Phillips, while extras wearing feather-adorned caps and 1920s flapper-style dresses walked around the set.
The show is jointly produced by Amazon Studios and BBC Studios.
Much of the shooting has taken place at a film studio in Bathgate.
Good Omens was created and written by Neil Gaiman.
Photographer Michael Gillen spent the day in Bo’ness to capture the excitement, and get a glimpse behind the cameras.
